Question

Please help me p(x)=x^3+7x^2+4x x =-2

Answer 1

I think it is asking to evaluate the function at x=-2, so you plug it in
\(p(-2)=(-2)^3+7(-2)^2+4(-2)\) and solve
\(p(-2)=-8+7(4)-8\)
\(p(-2)=28-16\)
\(p(-2)=12\)

Answer 2

thank you so much but it says using the remainder therorm so there si another part

Answer 3
